This invention relates to dispensing apparatus and especially apparatusfor dispensing liquids, as beverages. According to the in apredeterminedquantity (as a cupful) at a single dispensing operation, whereby themixture will be fresh when delivered and the entire apparatus may bemade quite compact.

One object of the invention is to provide for the dispensing in suchmanner that the mixing of the two liquids shall occur as-the result ofthe operation of dispensing; also that such mixing shall be as thoroughas possible. Another object is to insure that equal quantities shall bedispensed on successive operations, and that where, as usual, the flavoring liquid is a syrup the water shall act to cleanse the device by whichsuch syrup is measured. Another object is to provide for the dispensingof a cup with each quantity of liquid, or drink, dispensed, the cupbeing automatically placed in proper position to receive the drink; inthe preferred form the dispensin of the cup and then of the liquid iseffecte by operation of means common to both and single in character.Another object is to improve the means by which the dis pensing of thecups is effected.

closed in some suitable way. In this wall, at

about its middle, is a niche structure 6 and within the latter is acup-shaped cup-receiver 7 provision is made (as will appear) foradmission of the cups and also of the beverage to this niche structure,and it may have a small front glazed closure 8 normally held closed, asby a spring (not shown), and free- 1y openable by the customer. Door 5may also have an opening 9 through which the customers may deposit thewaste cups in the bin 3. Liquid dispensing.1n the chamber 4 is a Watertank 10 which is L-shaped in plan (Fig. 5). This is preferably jacketedin heat-insulating material 11, and it may contain a cooling coil 12adapted to form part of a system for keeping the water. in the tankcool, as by being suitably connected with the refrigerating unit 2. Inthis tank 10 is a syrup tank 13. The water tank 10 may stantiallyconstant is afforded by an ordinary and the float 16 controlling thevalve, closing it on rising and opening it on falling. I (17 is simply apartition to isolate the float from agitation of the water in tank 10incident to the movement of certain parts, as will appear). The syruptank receives its supply from the syrup reservoir 18 (Fig. 3) which isplaced above the tank 10 and has a discharge tube 19 reaching down intothe body of liquid (syrup) in the tank 13; the reservoir being closed tothe atmosphere a hying here also its fulcrum or pivot and penetrating asuitable gland or equivalent liquid sealing means 23 in the front walls(here face to face) of the tanks 10 and 13 (Figs. 5 and 6). When thedippers are depressed until submerged and then elevated the discharge ofthe water takes place via the syrup dipper, so that it does not becomefouled with more or less dried syrup.

The discharge of the liquids via tube 21 is into the nozzle 24 which, asshown in Fig. 8, debouches through ahole in the top of the nichestructure 6 into the cup deposited therein in receiver 7. The nozzle hasa chamber 24 provided with a bottom outlet 24 and with a dam 24. Withoutthis special construction there may be a tendency for the liquids to bedelivered to the cup so that there would be a quantum of pure syrup atthe bottom of the cup; but with it the flow of pure syrup proceeds moreslowly than it otherwise would (through outlet 24") while the body ofliquid consisting at first of more or less diluted syrup and ultimatelyof pure 'water sweeps over the syrup in chamber 24 and over the dam,with the result that the thick syrup, liquid is mixed with water when itreaches the cup and the final flow of clear water washes out the passageentirely.

The two dippers are connected to descend and rise together thus: Abifurcated plunger is formed by thehead 25 and two rods'26 and 27depending therefrom, these sliding in the fixed guide 28 (Fig. 3) andone being fixed to dipper 20 and the other having a pivotal connection27 a with one link 21 pivoted to dipper 21 at 21. tional resistance ofcontrol may be applied to the plunger by the brake-device 29 heldagainst one rod by a spring 30 subject to an adjusting screw 31 tappedinto said guide. The connection is in the example actually such, asindicated, that the dippers both rise and fall by movement of plungers26 and 27 but due to the link 21, connected as shown, the syrup dipper21 reaches the discharging position sufficiently ahead of water dipper20 so as to insure. against water backing up into the syrup supply tankin case the manually operated upstroke of plungers 26 and 27 should notbe entirely completed.

other.

Variable fric- 1, as to brackets 32-on its door 5, is an aunularhopper.33 in which is journaled the vertical shaft 34 having a head 35seated on the hopper and equipped with several upstanding cylindricalcup-holders 36; below the hopper the shaft has a ratchet-wheel 37 Thehopper has a chute 38 debouching downwardly into niche structure 6 so asto deliver each cup to the receiver 7. .The cups A are'of the typehaving exterior flanges AT at their mouths and their form is such thatwhen arranged in stacks, as shown, their flanges are a trifle spacedfrom each The rotary turret comprising the shaft, its head and theratchet-wheel is turned step by step, each stack of on s sliding on thebottom of the annular iopper' except in the region including thedowntake 32 of the chute, where the flange of the next from the bottomcup overrides two guides 39 on the hopper and that cup and all above itthen slide along on these flanges until the chute entrance or downtakeis passed, whereupon what is thus left of the ill) stack again slides onthe bottom of the hopper. The lowest cup (i. e., the one below the onewhich overrode the guides), when it reaches the chute downtake, ofcourse falls therethrough into the receiver 7. Preferably I the bottomof the hopper 33 has a step-down 33 just following the point where eachcuppressed pawl 40. Fulcrumed on the shaft 34 is a cup-feed-controlmember in the form of a pawl-lever 41 carrying a spring-pressed pawl 42engaged with the ratchet-wheel. said member being adapted on each returnor idle stroke to disengage the pawl 40 from the wheel. (Fig. 4.) Thusthe cup-conveyor is adapted to be rotated step by step.

Urea-controlled operating means.-In a casing 43 (Figs. 9 and 10) on thedoor 5 is a sleeve 44 having arms 44 and 44". Arm 44 has pivoted theretoa link 45 which slides in a. guide 46 pivoted in a bracket 47 attachedto door 5, and this link has an arm 48 which engages in a horizontalslot 25 of the head 25 of the before-mentioned dipper actuating plunger.Arm 44 is connected by a link 49 with the pawl-lever 41. Therefore eachtime the sleeve 44 is turned to the right it against backward movementby the spring I dippers are fully elevated and the raises the'plungerand the two dip ers, thus reducing the liquid delivery into t e placedward stroke is eflected through a coin'which.

interlocks the sleeve and barrel together and which is entered at acoin-slot 52 in the housing 5 and passes through casing 43 into slots 53in the sleeve and barrel provided all these slots register as in Fig.10, which shows the parts in the positions they occupy when thle awlever 41 fully retracted; atthe end 0 this stroke the coin falls througha chute 54 into,

a. coin-box 55. The anti-clockwise or return stroke of the sleeve iseffected by the knob-spindle through an arm 56 on the same which abutsthe arm 44 of the sleeve when the slotsof the spindle-barrel and sleeveare alined. Of course if-no coin is resent, movement of the knob-s indleis a rtive. It may be desired to stir the syrup in the reservoir 18 tokeep it throu hout of uniform consistency. Wherefore 5% is a propellerjournaled therein and havin a pinion 58 with which engages a rack 59aving a stem 60 which reaches down-through tube 19 and then up exteriorof reservoir 18, being connected by arm 61 withthe head 25 of theplunger.- Each time the latter descends'and rises the propeller isrotated back and forth. Having thus fully described my invention what Iclaim is:

pense the liquids therefrom including di pers immersible 1n andwithdrawable from t e respective liquids and means to immerse them intoreceiving relation to and withdraw them' from the liquids, one of saiddippers having means to discharge its liquid content into the other onsuch withdrawaland'the latter forming the discharge 'of said dispensingmechanism.

2.
